I company called ECA Program is in talks to purchase 15 Su-27 Flankers from Belarus in order to set up a private air-to-air combat academy at Keflavik airport in Iceland.
The primary customer is dissimilar air combat training for NATO forces, but I would really like to get a ride on one of these aircraft, and my guess is that they will make this available to private individuals as well.
Of course, now I just need a few million dollars.
I would also note that there are some differences of opinion amongst the various players in the Icelandic government about the merit of this proposal.
